If you walk the differential data and clock inputs of an NB7V52  CML flipflop across one another in time, the equivalent jitter is below 20 fs RMS. That's what we're measuring, but our test rig may well dominate the jitter, so the flop is probably better.

We're using this to test the jitter of some of our timing products, with 1/10 the noise floor and 1e-4 times the cost of other ways to do it.
